How to create a loop from a string based on a delimiter

Question

I have a string like this:

var string = ' [United States] [Canada] [India] ';

I want to do a for loop and add each of the countries into an array in Javascript or Jquery, something like this:

var countryArray = new Array();
for ( each country in string AS country) {
  countryArray.push(country);      
}

I'm not sure how I would make a foreach loop out of a string like that.

Did you try splitting the string with "[U] [C] [I]".split(' '); ? — Cengiz Can

Here:

var arr = str.match(/\[.+?\]/g).map(function (s) { return s.slice(1, -1); });

There's probably a better way to do it, though...

I would do it like this

string.match(/\[(.*?)\]/g).map(function(inp){return inp.substring(1, inp.length - 1)})

wow. exact same thing

Yea, pretty much :) I think it's possible to make the match method return the strings without the brackets, but I don't know how to do that....

split()?

var string = ' [United States] [Canada] [India] ';
var arr = string.split(/([[^[]*])/ );

alert(arr);

This won't work, as this will display the output like this - [United States,], [Canada,], [India,],. Please check here- jsfiddle.net/4yHp5
